Description

5G network element registration information auditing method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of 5G network element registration technologies, and in particular, to a method, an apparatus, an electronic device, and a storage medium for auditing 5G network element registration information.

Background

The AUSF registers information such as a number segment (including supiRanges) for providing service to NRF to which it is attributed, the UDM registers information such as a number segment (including supiRanges, gpsiRanges) for providing service to NRF to which it is attributed, the IWF registers information such as a number segment (including supiRanges, gpsiRanges) for providing service to NRF to which it is attributed, information such as a number segment (including supiRanges, gpsiRanges) for providing PCF for providing service to NRF to which it is attributed, information such as TA (including taiList, taiRangeList) for providing AMF for providing service to NRF to which it is attributed, and information such as TA (including taiList, taiRangeList) for providing SMF for providing service to NRF to which it is attributed. The 1 pair NRF can serve various 5GC network elements of multiple provinces. Under normal conditions, the group POOL or the network elements with the active-standby relationship provide the same service, different users or ranges are provided with services between different POOL and non-active-standby network elements, mutual exclusion relationship exists, and no crossed and overlapped scene exists.

Because the NRF is responsible for registering, deregistering, updating and other services of various 5GC network elements, relevant information (such as supiRanges, gpsiRanges, taiList, taiRangeList and the like) provided by various network elements is passively received, and verification on authenticity of information provided by various network elements is not yet provided, the problem that users access to network elements which cannot provide services due to non-matching, missed matching, mismatching and multiple matching of network element data information, and therefore service cannot be used, and the like is likely to occur. The specific problems are as follows:

1. The configuration conflict of the UDM/AUSF and IWF number segment data in the province causes the problems of unsuccessful authentication of the number segment user, unsuccessful downloading of subscription data and the like.

For example, due to the error of data configuration, the number segment 139H0H1H2H3 belonging to a certain UDM and a certain IWF also configure 139H0H1H2H3 information, or a large piece of 139H0H1H2 data is configured, the UDM and the IWF register or update the number segment information on the NRF to which they belong, respectively, and the NRF does not perform data authenticity verification, so that it is considered that both the UDM and the IWF can provide services for the user of the 139H0H1H2H3 segment. Therefore, some 139H0H1H2H3 segment users cannot find out the number segment data configuration conflict between different UDMs/AUSFs or different IWFs in the province.

2. The configuration conflict of the data of different PCF number segments in the province causes that the normal strategy data control cannot be carried out on the number segment users.

For example, due to a data configuration error, the number segment 139H0H1H 3 belonging to PCF1, PCF2 (not belonging to the same POOL as PCF 1) is also configured with 139H0H1H2H3 information, or a large piece of 139H0H1H2 data is configured, PCF1 and PCF2 register or update the number segment information to their home NRF respectively, and NRF does not perform data authenticity verification, so that it is considered that both PCF1 and PCF2 can provide services for the 139H0H1H2H3 segment user, thus resulting in that some 139H0H1H2H3 segment users cannot find their home PCF 1.

3. TA data configuration conflicts for different SMF POOL in the province result in that part of users perform normal services differently on a certain TA.

For example, due to a data configuration error, the TA LIST1 and the SMF2 (which are not the same POOL as the SMF 1) belonging to the SMF1 also configure TA LIST1 information, and the SMF1 and the SMF2 register or update the TA LIST1 information onto the NRF to which they belong respectively, and the NRF does not perform data authenticity verification, so that it is considered that both the SMF1 and the SMF2 can provide services for the user under the TA LIST1, and therefore, some users under the TA LIST1 cannot find their home SMF 1.

4. Under the same NRF, the conflict of UDM/AUSF configuration data among different provinces causes the problems of unsuccessful authentication of the number segment user, unsuccessful downloading of subscription data and the like. Because of the lack of effective communication and coordination mechanisms between different provinces and the possibility of adopting equipment of different manufacturers, the data configuration modes are not uniform, for example, the A province UDM/AUSF configures full-quantity number segment information, including the B province number segment information, and the problem that the A province configuration data is wrong and the B province user cannot normally service is caused.

5. Under the same NRF, PCF configuration data conflict among different provinces, so that normal policy data control cannot be performed on the number segment users. Because of the lack of effective communication and coordination mechanisms between different provinces and the possibility of adopting equipment of different manufacturers, the data configuration modes are not uniform, for example, PCF configuration full-quantity number segment information of the province A comprises number segment information of the province B, thereby causing the problem that the configuration data of the province A is wrong and the normal service of the user of the province B cannot be influenced.

6. Under the same NRF, the conflict of SMF configuration data among different provinces causes that partial users do normal business differently on a certain TA. Because of the lack of effective communication and coordination mechanisms between different provinces and the possibility of adopting equipment of different manufacturers, the data configuration modes are not uniform, for example, the SMF of the province A does not configure TA information (equivalent to the TA information capable of serving all), so that the problem that the user of the province A cannot normally service due to the fact that the configuration data of the province A is wrong is caused.

Therefore, how to avoid the problem that the existing network element functional body registration information audit has a long process caused by manual work and greatly delays network access time, and the inability to automatically audit the configuration data of various different network element functional bodies is still a urgent problem to be solved by the technicians in the field.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The existing network element functional body registration information auditing generally has the problem that the network access time is greatly delayed due to the flow length caused by manual work, and the configuration data of various different network element functional bodies cannot be automatically audited. The following describes a method for auditing 5G network element registration information according to the present invention with reference to fig. 1 to 5, where the execution body is NRF (NF Repository Function, network storage function). Fig. 1 is a flow chart of a method for auditing 5G network element registration information provided by the present invention, as shown in fig. 1, the method includes:

step 110, receiving registration information sent by any 5G network element, and extracting all identification bytes matched with a preset registration information format in the registration information, wherein all the identification bytes at least comprise IPv6 bytes.

Specifically, the execution main body of the auditing method of 5G network element registration information provided by the invention is NRF, which is a functional body for managing all network elements belonging to the network, all network elements belonging to the network need to register on the network, self hardware information, service information, self type information, configuration information and the like are provided for storage on the NRF, and when the self state changes, update information is sent to the network to update the information stored before; the NRF stores information belonging to the network element function body managed by the NRF, when a request for using a certain service of a certain network element function body is made by the network element function body from other clients or the network element function body of the NRF, the NRF is used as a function body similar to a DNS server function, the address information and the service information registered by the requested network element function body on the NRF are queried, and if the service can be provided, the address of the requested network element function body is returned to a requester for direct access. When the NRF receives registration information sent by any 5G network element, all identification bytes matched with a preset registration information format in the registration information are firstly extracted, wherein the preset registration information format is a field bit sequence and a bit number of various identification bytes integrated by various information in the preset registration information, for example, the preset registration information format comprises a field bit sequence and a bit number of two identification bytes of a designated network element instance identifier NF instance ID and a network element Group ID, the designated NF instance ID comprises 6 bytes, the first byte is used for storing NF type codes, the second byte is used for storing the belonging area codes, the third byte is used for storing the belonging province codes, the 4 th to 6 th bytes are used for storing the instance sequence number codes, the designated Group ID comprises 5 sub-identifications, and sequentially the first sub-identification uses 1-8 bit letters to represent NF types, the second sub-identification uses 6-7 bit letters to represent the belonging area, the third sub-identification uses 2 bit letters to represent the belonging province, the fourth sub-identification uses 2-bit letters to represent the belonging area, and the fifth sub-identification uses the NF number letters to represent the belonging area codes. That is, the field bit order and bit number of each existing identification byte are uniformly specified in the preset registration information format, the identification bytes contained in the registration information in any 5G network element can find the corresponding format in the preset registration information format, the registration information sent by the 5G network element under normal conditions should also be formed by the identification bytes constructed according to the field bit order and bit number specified in the preset registration information format, the identification bytes contained in the registration information are limited to include only IPv6 bytes, other identification bytes are selected according to the network element types, for example, the network element which is responsible for the same service as some other network elements, the registration information provided by the network element can include three identification bytes of network element instance identification NF instance ID, network element Group identification Group ID and IPv6 bytes, and also can include two identification bytes of network element Group identification Group ID and IPv6 bytes, so that in order to ensure the correctness of the registration information, the network element which is not explicitly defined here can provide a plurality of identification bytes, the redundant information generated by each identification byte can be used as a source for determining whether error-checking information needs to be filled back to each other. Here, the registration information described in step 110 refers to not only the registration information that the network element function sends to the NRF for the first time, but also updated registration information that the network element function sends to the NRF when it needs to update the registration information according to its own status after successful network access.

And step 120, judging whether the area information extracted from the IPv6 byte is consistent with the area information extracted from other identification bytes in all the identification bytes based on a preset number comparison table and whether the service information extracted based on the other identification bytes is not in conflict with the pre-stored registered service information or not.

Specifically, the execution body of the method provided by the invention has a pre-stored preset registration information format to assist in extracting various identification bytes in the received registration information, and a pre-stored preset number comparison table, wherein the preset number comparison table is equivalent to a translation table, translates coding information in various identification bytes in the registration information into own hardware information, service information, own type information and configuration information of a network element, and the like, for example, the preset number comparison table comprises a number segment table with the province information as an index, a host name table with the province information as an index and an IPv6 address table with the province information as an index, so that the corresponding provinces of the host coding information, the number segment coding information and the IPv6 information in various identification bytes can be translated according to the three tables, if the corresponding provinces are consistent, through mutual verification among byte identifications, otherwise, filling errors of a certain byte identification need to be returned. The above examples are based on mutual checking between byte identifiers implemented by querying a preset number comparison table, and the auditing process further includes conflict checking between the registered information and registered information stored in the NRF. For example, for the case that the NRF has a similar network element (belonging to a master-slave relationship or belonging to the same POOL) with the registered network element, service information (such as segment number or TA information) of the registered network element is required to be the same as that of the registered similar network element, that is, the registration of the similar network element is required to ensure that certain attribute (that is, service information) of the similar network element is consistent to embody the similar relationship; for the case that the same type of network element (belonging to the main-standby relation or the same POOL) exists in the NRF, service information (such as segment number or TA information) of the network element to be registered is different from that of all registered network elements in the NRF (i.e. no intersection exists), so that the service information of the new type of network element to be registered to the network is ensured to be not repeated with that of the registered service information, and the novelty of the network element type is reflected.

And 130, if yes, storing the registration information, otherwise, returning a rejection registration response to any 5G network element.

Specifically, only if the registration information passes both the mutual check between the identification bytes carried by the registration information and the conflict check between the registration information and the registered information stored in the NRF, that is, if both checks pass, it is determined that the registration information is accurate, and any 5G network element approved to send the registration information can be stored for network access, otherwise, that is, if one check fails, a rejection registration response is returned to any 5G network element, and the rejection registration response may further include an instruction for requesting refill of some identification bytes, indicating that a specific identification byte possibly has an error facilitates the targeted check and modification of the registration request network element, thereby improving the efficiency of resending the registration information.

According to the auditing method of the 5G network element registration information, all the identification bytes matched with the preset registration information format in the registration information are extracted by receiving the registration information sent by any 5G network element, wherein the all the identification bytes at least comprise IPv6 bytes; judging whether the area information extracted from the IPv6 byte is consistent with the area information extracted from other identification bytes in all the identification bytes based on a preset number comparison table and whether the service information extracted based on the other identification bytes is not in conflict with the pre-stored registered service information or not is met at the same time; and if yes, storing the registration information, otherwise, returning a response of refusing registration to any 5G network element. The preset registration information format and the preset number comparison table are set, so that the NRF can automatically match various contents in the registration information after receiving the registration information, perform mutual verification on the various contents and conflict verification on the various contents and the registration information stored in the NRF, thereby achieving the purpose of error detection and verification, automatically checking the registration information of various network elements, and avoiding network element network access time delay caused by high labor cost and long time consumption of manual checking. Therefore, the method provided by the invention realizes automatic auditing of the configuration data of various network element functional bodies, and avoids network element network access time delay caused by high labor cost and long time consumption of manual auditing.

On the basis of the above embodiment, in the method, the other identification bytes include any one or more of a network element instance identification, a network element group identification, a fully defined domain name, and a configuration identification specific to any 5G network element;

Specifically, the preset registration information format is defined herein, where the preset registration information format is a format for specifying field bit sequences and bit numbers of four identification bytes including a network element instance identifier, a network element group identifier, a fully defined domain name, and any one of the 5G network element specific configuration identifiers, and the four byte identifiers cover all types of identification bytes included in all registration information or update information in the network, that is, one registration information, except that IPv6 bytes are necessary to carry bytes, and other identification bytes are any combination of any one or more of four identification bytes including a network element instance identifier, a network element group identifier, a fully defined domain name, and any one of the 5G network element specific configuration identifiers. The preset registration information format clearly specifies in which field bit order and bit number the four identification bytes encode, encapsulate and store the network element information that they need to carry, and the network element information that they need to carry is, for network element instance identification, network element group identification, full-defined domain name and any 5G network element unique configuration identification, the four identification bytes are in turn region information and service information combination, region information and host information combination, and unique configuration. The other identification bytes are obtained by removing IPv6 bytes from all the identification bytes matched with the preset registration information format, so that the other identification bytes are all identification bytes meeting the requirement of the preset registration information format.

On the basis of the above embodiment, in the method,

the method comprises the steps that whether the area information extracted from the IPv6 byte is consistent with the area information extracted from other identification bytes in all identification bytes based on a preset number comparison table and whether the service information extracted based on the other identification bytes does not conflict with the prestored registered service information or not is judged; if yes, storing the registration information, otherwise, returning a response of refusing registration to any 5G network element, wherein the response specifically comprises the following steps:

Specifically, for any 5G network element being an AUSF function, a UDM function, a PCF function, or an IWF function, the process of determining whether the area information extracted from the IPv6 byte is consistent with the area information extracted from other identification bytes in all the identification bytes based on a preset number comparison table and whether the service information extracted from the other identification bytes and the pre-stored registered service information do not conflict to meet both checking requirements simultaneously may set a condition reducing the complexity of the determination, achieving the effect of identifying the registration information with the least number of steps that is the fastest, thus, firstly, determining whether the service information extracted from other identification bytes in all the identification bytes (here, the configured number section) is empty, if yes, returning a rejection registration response to any 5G network element, otherwise, selecting the IPv6 byte for which the address information is the easiest to find, directly extracting the identification province byte in the IPv6 byte, then determining whether the identification province byte information thereof is met, then extracting all the area numbers in other identification bytes in all the identification bytes, determining whether the corresponding to all the identification bytes in all the identification bytes are not met, checking the registration request is performed by checking the corresponding to any other identification bytes, if no registration request is met, and if no registration request is sent to all the identification bytes is detected by any other identification bytes, if no registration request is detected by comparing the identification byte with the preset number information in all the identification bytes, and if no registration request is found by comparing the identification byte with all the identification bytes in all the identification bytes, here, the probability that all the province information provided in the identification bytes is simultaneously erroneous is 0 (because the address information provided in IPv6 can be accurate by default, and the address information provided in IPv6 can be used as a reference value); after mutual verification between the identification bytes, it is determined whether there is a conflict between the registration information and registered information stored in the NRF. Firstly, if any 5G network element is an AUSF function body, a UDM function body, a PCF function body or an IWF function body, traversing the host name of a registered network element stored in an NRF, judging that a 5G network element which sends a registration request has a host with a host-backup relation in the NRF based on host name information carried in other identification bytes in the registration information, extracting service information of the 5G network element which needs to be registered, comparing the service information of the 5G network element with the service information of the host with the host-backup relation, if the service information is the same, storing the registration information without conflict, confirming that any 5G network element is successful in network access, and otherwise, returning a refusing registration response to any 5G network element; if the host name of the registered network element stored in the NRF is traversed, and based on host name information carried in other identification bytes in the registration information, it is determined that the 5G network element sending the registration request does not have a host with which the host has a master-slave relationship in the NRF, whether service information in registration information of the 5G network element needing to be registered is repeated with service information of the network element already registered in the NRF is detected, if the service information is not repeated, it is determined that no conflict exists, the registration information is stored, and the network access of any 5G network element is determined to be successful, otherwise, a rejection registration response is returned to any 5G network element. Because any 5G network element refers to the case that it is an AUSF function, a UDM function, a PCF function, or an IWF function, the service information related thereto is a number segment configured by the AUSF function when the network element function is an AUSF function, a number segment configured by the IWF function when the network element function is an IWF function, and a number segment configured by the PCF function when the network element function is a PCF function.

Firstly, if any 5G network element is an SMF functional body, traversing the host name of a registered network element stored in NRF, judging that the 5G network element sending a registration request has a host with a main POOL relation in NRF based on host name information carried in other identification bytes in registration information, extracting specific configuration information of the 5G network element needing to be registered, then comparing service information of the 5G network element with the specific configuration information of the host with the main POOL relation, if the service information is the same, storing the registration information without conflict, and confirming that the network access of any 5G network element is successful, otherwise, returning a refusal registration response to any 5G network element; if the host name of the registered network element stored in the NRF is traversed, and based on the host name information carried in other identification bytes in the registration information, the 5G network element sending the registration request is judged to have no host with which the host has a main POOL relation in the NRF, whether specific configuration information in the registration information of the 5G network element needing to be registered is repeated with the specific configuration information of the network element already registered in the NRF is detected, if not, no conflict is judged, the registration information is stored and confirmed to be successful in network access of any 5G network element, otherwise, a rejection registration response is returned to any 5G network element. Since any 5G network element refers to the case where it is an SMF function, the specific configuration information referred to therein is taiList and tairange list, etc. when the network element function is an SMF function.

On the basis of the above embodiment, in the method,

Specifically, for any 5G network element being an AMF function, the process of determining whether the extracted area information in the IPv6 byte is consistent with the area information extracted from other identification bytes in all identification bytes based on a preset number comparison table and whether the two verification processes are satisfied simultaneously due to non-collision between the service information extracted from other identification bytes and the pre-stored registered service information may set a condition for sequentially determining to reduce the complexity of the determination, so as to achieve the effect of identifying the registration information with the least determination step fastest, where the TA information extracted from other identification bytes in all identification bytes is empty, if yes, a rejection registration response is returned to any 5G network element, otherwise, the IPv6 byte with the highest possibility of searching address information is selected, the byte with the identification province in the IPv6 byte is directly extracted, then all the area numbers corresponding to all the area numbers are determined based on the preset number comparison table, when the latest identification with the least determination step is achieved, the registration information with the default is not provided, and the mutual identification byte is not completely visible, if no mutual registration is provided by the 0, if no mutual identification is provided by the mutual identification byte in the default, if no mutual identification byte is provided, if no mutual registration is provided by the 0, address information provided in IPv6 may be used as a reference value); after mutual verification between the identification bytes, it is determined whether there is a conflict between the registration information and registered information stored in the NRF. Firstly, if any 5G network element is an AMF functional body, inquiring a preset number comparison table based on the area identifier and the set identifier to determine whether the POOL to which the any 5G network element belongs carries out conflict judgment with registered information, and judging whether conflict exists between the registered information sent by the any 5G network element and the registered information stored in the NRF. Firstly, under the condition that any 5G network element is an AMF functional body, if the registered network element stored in the NRF is traversed, and the 5G network element sending the registration request is judged to have a host with the same POOL relation as the home country in the NRF, the 5G network element needing to be registered extracts the TA information of the 5G network element and then compares the TA information of the 5G network element with the TA information of the host with the same POOL relation as the home country, if the TA information is the same, no conflict exists, the registration information is stored, the network access of any 5G network element is confirmed to be successful, the registration information is stored, and otherwise, a response refusing the registration is returned to any 5G network element; if the registered network elements stored in the NRF are traversed, judging that a host with the same POOL relation exists in the NRF, detecting whether TA information in registration information of 5G network elements needing to be registered is repeated with TA information of network elements already registered in the NRF, if not, judging that no conflict exists, storing the registration information, judging that the network access of any 5G network element is successful, and otherwise, returning a response of refusing the registration to any 5G network element. Since any 5G network element is singly referred to as an AMF function, the POOL concerned is an AMF POOL.
